While the team has already conducted interviews with Horton and plans to do so with McCoy in Denver this weekend, Reid will now reportedly be taking his talents to Kansas City in a drastic turn of events.

The Cardinals have since searched far and wide for a coach, and as of now they’re still looking.

ArizonaSports.com has learned through sources that Indianapolis Colts offensive coordinator Bruce Arians will not retain Ray Horton as defensive coordinator if he indeed lands the vacant Arizona Cardinals head coaching job.

Bengals offensive coordinator Jay Gruden confirmed Tuesday the Cardinals and Eagles have received permission to interview him for their head coaching jobs and indications are he’ll visit Arizona later in the week.

Gruden just completed his second season in Cincinnati — both of which ended in playoff appearances for the Bengals. Cincinnati’s offense ranked 22nd in the league in total yards in 2012 and 12th in scoring. In 2011, the Bengals offense ranked 20th in yardage and 18th in scoring.

Andy Reid appears unlikely to be come the Cardinals’ next coach, with a source telling The Associated Press on Thursday that Reid is in negotiations with the Chiefs to become head coach and has canceled plans to interview for other openings, including the one in Arizona.

Andy Reid is in his second day meeting with Chiefs officials and that process has been going well, according to a source with knowledge of the situation. Reid was originally scheduled to arrive in Arizona to interview with the Cardinals on Wednesday.

Ray Horton laid out his plans to Michael Bidwill during a give-and-take talk, Horton said, covering everything from players and coaches to potential remodeling of the Cardinals’ Tempe facility and the type of grass used on the practice fields.

There has been much speculation about who will take over the head coaching reins of the Arizona Cardinals. One name that has been linked frequently to the Cardinals is former Philadelphia Eagles head coach Andy Reid.

While Ray Horton has proven himself at each of his five NFL stops (Washington Redskins, Cincinnati Bengals, Detroit Lions, Pittsburgh Steelers and Arizona Cardinals), one ESPN insider isn’t so sure he’s ready for the promotion.

Just hours after the Arizona Cardinals announced that they had fired head coach Ken Whisenhunt and general manager Rod Graves, names started surfacing for the job openings, including former head coach Andy Reid.
